The project scope of works involved re-roofing, painting and restoration works included:
Benledi House was constructed in the late 1880’s in the Italianate style of the period. As part of the works, Murphy’s redecorated and restored many of the original period features including the window frames and railings. Ornamental embellishments were specially re-cast to restore the heritage decorations andfinishes of the original building. All works were performed to the specifications of the heritage architect.
Samples of finishes were provided to the City of Sydney Council for their approval included paint finishes, roof tiles, gutters, downpipes and fixings. The principal work activity of the project was the renewal of Benledi House roof. The roof was replaced progressively, that is each section removed was reinstated each day. In this way, the building remained water tight for the duration of the project. Tiles were removed from the roof and sent to the site recycling bin using the scaffold mounted tile chute. The existing sarking and roof battens were removed and replaced. 6mm thickness fibre cement sheeting was laid for anti-ponding.
Our experienced tilers then laid slate-look terracotta tiles, in line with the requirements of the client and heritage architect. All the five chimneys were dressed with lead flashings to make watertight the joins with the roof. New 0.55mm base metal thickness parapet cappings were installed as specified. Eaves guttering around the building was replaced. To complete the roof, an anchor point and ladder access bracket access system was added.
On closer pre-start inspection of the ceiling insulation works, Murphy’s suspected the presence of hazardous materials. The client was advised and engaged an independent occupational hygienist to carry out testing. High-level lead dust was found. Murphy’s removed this hazardous material by HEPA vacuuming and wet-wiping the floor, structural members and all surfaces within the ceiling space. This was carried out before the re-roofing of the building.
The independent hygienist then made a thorough inspection before issuing a clearance certificate to confirm the area was clear.
